Genetic Screening of Dowling-Degos Disease / Galli-Galli Disease

Dowling-Degos disease is a pigmentary disorder of the skin characterized by reticular hyperpigmentation with generally a flexural distribution. Acantholysis is seen in some cases, and is generally classified as Galli-galli disease, though the general consensus is that Dowling-Degos and Galli-Galli disease are the spectrum of the same disease. The disease is extremely rare with only a handful of cases reported in literature and the population frequency is unknown. Several cases of the disease has been described previously from India and around the world.
